I have a workflow designed to copy metadata from one file to another in the same list. We write documents in Word, but publish them as PDFs and the workflow is designed so that we don't have to manually re-enter all that data a second time.
Everything works fine, except for the data in a Choice column we have. It allows for multiple selections. If I use the default setting, which copies it as a string, no data copies over.
If I use the other option, Choices, Comma Delimited, the workflow errors out and I get this error:
Coercion Failed: Input cannot be null for this coercion.
I received the error once before while copying over data from a people-picker field where choices are delimited by semi-colons. In that instance, I found that copying the data as a string would solve the problem and now that data copies successfully.
What gives with the Comma-delimited columns not copying? This workflow automates a lot for us and will save us steps, but it has this one tiny hiccup I can't seem to make go away.
Any help would be appreciated.
Thanks,
